Application is finely arranged, in the upper part of the screen there is a graph with all 5 categories and the presence of applications in each. Maybe AppDJ is not best if you search a specific category, because there are so many, and here the App offer only 5. So you will have to search a little more to find what you want. For example, security tools are placed in the category of Productivity, multimedia tools are located in the Entertainment and customization tools in Lifestyle.
Also, you can easily set АppDj to give you information only for certain categories or a certain category to be a priority. For example, you can choose to receive recommendations for all popular applications of the category "Entertainment", or simply you want to receive applications only from "Productivity".
If you want to follow only popular applications from a particular category, increase the popular bar to the max, and trendy bar to a minimum, and set the remaining three bars at the same level. Once you make the change, the application will automatically update its list of recommendations.
The only disadvantage of the application is that there is no possibility to search only for free, or only for paid applications, and there is no information about whether is free or not by the name of the application. So, the user must click on the application to see all the other specifications like price, photos and description for it.
AppDJ is freely available on Google Play market.
